How to choose the right waterproof IP Level for an Outdoor led display ? 

Select the IP level of attention to environmental matching:

 Coastal areas need to IP67 or more (anti-salt spray corrosion).

Northern winter need to take into account the waterproof and low temperature resistance (-20 ℃ below the IP66/67).

Balance between heat dissipation and protection:

High IP ratings (e.g. IP68) may sacrifice the efficiency of heat dissipation and require additional design of heat dissipation channels.

Cost control:

 IP67/IP68 is 30%-50% higher than IP65, so it should be chosen according to the budget.

Maintenance Recommendations

Regular Inspection: Quarterly check whether the sealing tape is aging and whether the drainage holes are blocked.

Cleaning method: use a soft cloth to wipe, avoid high-pressure water gun direct spray (unless labeled to support IP66 or above).

Troubleshooting: Immediately disconnect the power after water ingress, contact a professional to disassemble and dry.

Summarize

The IP waterproof grade of LED outdoor display needs to be selected according to the specific environment:

 conventional outdoor: IP65 (cost-effective and optimal).

Harsh environment: IP66/IP67 (resistance to heavy rain, anti-submergence).

Special scenarios: IP68 (long-term underwater or extreme conditions).

Reasonable selection of IP rating and regular maintenance can significantly improve the reliability and service life of the display.
